Emotional/tearing up loads

I am getting a bit worried because I’m still being very emotional and I tear up quite often like most days I’d say. Especially when I look at my baby because I just have so much love for her but also if I’m watching something and it’s not even a sad scene but if it makes me feel emotional, I just start almost crying. My partner has gone away for work this morning and won’t be back till tomorrow and this is the first time he’s away overnight since we’ve had the baby and I just couldn’t stop crying about it last night and I keep getting teary eyes today too. Baby also had her jabs today and I almost lost my shit at the doctors when she cried as the nurse stuck the needles in her thighs and I had to force myself to not cry. It’s literally the same as it was when I was pregnant and I’m terrified I could be pregnant again even though we’ve been using condoms every single time and I’m breastfeeding so I think I’ve had one period so far but it didn’t feel like a proper one as it wasn’t very heavy so I have no idea what my cycles are doing atm. Can someone tell me what’s happening, is this normal after having a baby? It’s like my emotional state hasn’t gone away after I gave birth.. it’s been like this since a year ago when I got pregnant. I’m not depressed before someone says, like I’m absolutely fine, I do suffer from anxiety but I’ve had that for years even before I had my baby so not sure why I keep almost crying and getting really emotional 🥲🤣
